SPECIFICATION forming part of Letters Patent No. 621,658, dated March 21, 1899.

Application iiledoetober 25,1898. Serial No. 694,537. on model.)

To all whom it may concern:

Be it known that I, OLAUs L. GRIMSRUD, of Lead, in the county of Lawrence and State of South Dakota, have invented a new and use- 5 ful Improvement in Vehicle=Wheels, of which the following is a full, clear, and exact description.

My invention relates to the construction of vehicle-wheels, and especially to the construc- I tion of elastic tubular tires and rims for the same.

The object of the invention is to provide a tubular elastic tire that need not be inflated, and to construct such a tire and a rim there- I for in a simple, durable, and economic manher and so that the parts may be quickly and conveniently assembled and secured.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi- 2 5 cate corresponding parts in all the figures.

Figure 1 is aside elevation of a portion of a wheel rim and tire constructed in accordance with my invention. Fig. 2 is a trans- Verse section through the improved rim and 3e tire, the view being on alarger. scale than that shown in Fig. 1; and Fig. 3 is a detail perspective view of a portion of an expanding or shaping section used in the construction of the device.

The rim consists of two sections 10 and 11, made of wood, metal, or other suitable material, having their opposing faces concaved from their outer longitudinal edges to a point near their inner longitudinal edges. The e space between the outer longitudinal edges of the sections of the rim substantially corresponds to the outer diameter of the tire B -to be employed, while the two sections at their inner edges are brought quite close together to form a trough 12, which trough in cross-section is practically rectangular, as

shown in Fig. 2, although said trough may be of any other cross-sectional shape.

I The rim-section 10 is provided with a flange 5'0 13 at its inner longitudinal edge, the flange being at a right angle to the body of the section, and this flange forms what may be termed the bottom of the trough 12, as the inner longitudinal edge of the opposing rimsection 1]. bears against the said flange, as shown in Fig. 2. In the construction of the tire an endless strip or belt of rubber or other elastic material is employed. When con structing the rim' and tire, one longitudinal edge of the belt is made to rest upon the flange 13 of the section 10 and an expanding of the tire-belt B, which will have assumed a tubular shape, as disclosed in Fig. 2, and a part of the sides of the tire thus constructed will be securely held between the expanding The belt is then carried around or shaping section and the sections 10 and 11 s of the rim.

It is evident that the tire need not be inflated, since the elasticity of the material employed'and the manner in which the tire is fitted in the rim andthe rim is constructed will cause said tire to remain expanded. The spokes 16 of the wheel are secured to the rim by entering them in a suitable manner into the flange 13 of the rim-section 10.

The expanding or shaping section 15 may be constructed of any desired material; but a spring materialsuch as brass, steel, or other metalis preferably employed, and the same material may be utilized in the construction of the rim.

Having thus described my invention, I claimas new and desire to secure by Letters Patent A wheel, having a rim and a tire, the rim being formed of two rigid sections, the outer portions of whichare flared outwardly to receive the tire, and the inner portions of which are converged toward each other to form a trough, the inner edge of one'of the sections having a flange thereon and the flange meeting the inner edge of the other section, and

the tire being formed of a section of flexible compressing the same against the outer pormaterial the edges of which are introduced tions of the sections of the rim. between the inner portions of the sections of the rim, fastening devices passing through OLAUS GRIMSRUD' 5 the inner portions of the sections of the rim and the adjacent portions of the tire, and an expanding section located in the tire and WVitnesses:
